Share 'Hair Dilemma - Desperately Need Your Advice, Guys'

Hi guys, How are you? I was wondering if you could help me decide which hair color and hair-do to choose. Currently my hair is brown and curly (like in the pic. on the right), but I was thinking, maybe it was better when it was black and straight (on the left)? I am going to a salon on Tuesday and frankly, I am clueless, so I wonder which of these 2 hair styles you like more? Thank you so ...
